ABSTRACT:
Polymeric hydridothiosilazanes, processes for the preparation thereof, silicon nitride-containing ceramic materials which can be prepared therefrom, and the preparation thereof.
The invention relates to novel polymeric hydridothiosilazanes, the preparation thereof, the conversion thereof into silicon nitride-containing ceramic material, and this material itself. To prepare the polymeric hydridothiosilazanes, oligohydridoalkylsilazanes (RSiHNH).sub.n are reacted with elemental sulfur and ether as solvents. The polymeric hydridothiosilazanes can then be pyrolyzed to form silicon nitride-containing ceramic material.
